A-2 Industio CP-114 User's Manual
configuration for IRQ and I/O addresses is automatically assigned by the PCI BIOS. Hence, you must
first plug the board before installing the software driver.
Unlike ISA slots, different PCI slots in the same PC may have different bus numbers and device
numbers with respect to the PCI specifications. The same PCI board will have different system
configurations if switching to a different PCI slot, which may be called slot-sensitive or
slot-dependent. This may also apply to PCI slots in PC with different motherboard, which may use
different device number sets. For example, some use 17, 18, 19, and 20 for identifying the
respective PCI slots but some use 11, 12, 13 and 14.
Due to the slot-dependency, it is necessary to re-configure the software driver once the
board is plugged in different PCI slots.
Up to 4 Industio CP-114 Series boards are allowed in one system. When installing more than one board,
please remember the order of boards for distinguishing the installed boards.
UART 16C550C
The UART chip, 16C550C, is an intelligent asynchronous controller capable of supporting one full
duplex channel that simultaneously transfers data at 921.6 Kbps. To increase the overall data
throughput, special features such as on-chip FIFO and on-chip hardware flow control are used to
reduce the number of interrupts to the onboard CPU and to prevent any loss of valuable data.
